Question

我拥有一些.a文件，并希望使用ndk-build生成.so。

Android.mk

LOCAL_PATH  := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := nonfree
LOCAL_MODULE += opencv_java3

LOCAL_SRC_FILES :=              \
    libopencv_aruco.a           \
    libopencv_bgsegm.a                  \
    libopencv_bioinspired.a     \
    libopencv_calib3d.a     \
    libopencv_ccalib.a     \
    libopencv_core.a     \
    libopencv_datasets.a     \
    libopencv_dnn.a     \
    libopencv_dpm.a     \
    libopencv_face.a     \
    libopencv_features2d.a     \
    libopencv_flann.a     \
    libopencv_fuzzy.a     \
    libopencv_highgui.a    \
    libopencv_imgcodecs.a    \
    libopencv_imgproc.a    \
    libopencv_line_descriptor.a    \

    libopencv_photo.a    \
    libopencv_plot.a    \

    libopencv_xfeatures2d.a   \
    libopencv_ximgproc.a   \
    libopencv_xobjdetect.a   \
    libopencv_xphoto.a

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include

include $(PREBUILT_STATIC_LIBRARY)

使用NDK-build使用这些steps。

当试图生成.so时，这会给我带来这个错误：

C：\ Android \ sdk \ ndk-bundle \ build \ ndk-build.cmd clean Android NDK：   jni / Android.mk中的LOCAL_MODULE定义不得包含空格
  C：/ Android设备/ SDK / NDK束/建立//../构建/核心/ build-shared-library.mk：23：   *** Android NDK：请更正错误。中止。停止。

处理完成，退出代码为2

LOCAL_MODULE指定构建的最终.so文件的名称。自space is introduced in the name when you concatenate the two strings nonfree和opencv_java3以来，ndk-build发出错误：

LOCAL_MODULE := nonfree
LOCAL_MODULE += opencv_java3

如果您想要连接名称，我建议您手动执行此操作：

LOCAL_MODULE := nonfree_opencv_java3

然后，当您通过JNI加载.so文件时，需要指定此名称。
